SI823H1BB-IM1R

Isolators - Gate Drivers Overview

The SI823H1BB-IM1R is a dual-channel isolated gate driver from Skyworks Solutions, housed in a 14-QFN package. It provides automotive-grade AEC-Q100 qualification with 5.0 kV isolation voltage. The device features non-inverting logic and supports a supply voltage range of 3 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 30 ns, rise and fall times of 12 ns each, and a continuous output current of 4 A per channel with a 6 A peak capability.

Isolators - Gate Drivers Feature Summary

• Provides robust 5.0 kV capacitive coupling isolation for high-voltage applications
• Integrates over-temperature protection and driver-side under-voltage lockout (UVLO) for enhanced safety
• Delivers high-speed switching performance with low propagation delay and symmetric rise/fall times

Isolators - Gate Drivers Applications

• Automotive power electronics systems requiring certified isolation
• High-side and low-side MOSFET or IGBT driving in motor control
• Industrial inverter and converter topologies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IM1R' corresponds to the tape-and-reel packaging variant rather than tube packaging when sourcing. Confirm that the AEC-Q100 qualification status is maintained for the reel configuration. Ensure compatibility with the 14-QFN footprint and check moisture sensitivity levels prior to soldering. Cross-reference the manufacturer's latest datasheet to confirm pinout consistency with previous revisions.

Isolators - Gate Drivers Selection Notes

Select this component when 5.0 kV isolation is required alongside automotive reliability standards. The 4 A continuous output current suits medium-power MOSFETs, while the 6 A peak handles fast switching transients. Consider the 14-QFN form factor for compact PCB layouts. Verify that the non-inverting logic configuration aligns with the control signal requirements of the target application circuit.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of isolated gate drivers designed for demanding power conversion environments. The series emphasizes safety through integrated protection mechanisms and high isolation ratings. The IM1R designation indicates a specific reel-based packaging option within the broader product line, maintaining identical electrical characteristics to other variants in the family.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same family include SI823H1BB-IS1 for tube packaging. Other variants like SI823H1BD-AS3 offer similar functionality in different packages. Always verify pin-to-pin compatibility and isolation voltage ratings before substitution.
